Copper Corrosion Inhibitors

Tolyltriazole Sodium Salt (TTA·Na) – Water-Soluble Corrosion Inhibitor

Tolyltriazole Sodium Salt (TTA·Na) is the neutralized salt form of TTA, typically supplied as an amber transparent liquid (50% concentration) for ease of dosing in aqueous systems. It is widely recognized as one of the most effective “yellow metal” inhibitors in the water treatment industry.

Unlike the acid form, the sodium salt is highly soluble in water, making it the preferred choice for automated dosing systems in cooling towers, heat exchangers, and closed-loop systems.

Why Choose TTA·Na?

• Superior Film Formation: It adsorbs onto the metal surface to create a micro-thin, uniform barrier against corrosive agents and atmospheric oxygen.
• Synergistic Performance: When used in combination with MBT (Mercaptobenzothiazole) or phosphonates, its protective effect is significantly enhanced.
• Multi-Metal Protection: While specialized for copper, it also provides effective secondary protection for “black metals” (ferrous metals).
• Ease of Application: Being a liquid salt form, it integrates seamlessly into alkaline water treatment formulations without requiring pre-dissolving in solvents.
